Cette bougie de préchauffage (100) est équipée : d'un logement à peu près cylindrique qui s'étend dans la direction axiale ; d'une unité de chauffage en forme de tige, dont la pointe dépasse de la pointe du logement, et qui peut se déplacer dans la direction axiale ; d'un élément de liaison qui relie l'unité de chauffage et le logement dans l'intérieur du logement tout en permettant à l'unité de chauffage de se déplacer dans la direction axiale ; et d'un capteur de pression qui détecte la pression subie par l'unité de chauffage. Un élément de diamètre épais est formé à l'extrémité arrière de l'unité de chauffage, et un élément de diamètre mince ayant un diamètre inférieur à celui de l'élément à diamètre épais est formé plus près de l'extrémité avant que ne l'est l'élément à diamètre épais. L'élément de liaison relie l'élément à diamètre mince de l'unité de chauffage et le logement dans l'intérieur du logement.
